### What it does

Disallow using deprecated `destroyed` and `beforeDestroy` lifecycle hooks in Vue.js 3.0.0+.

### Why is this bad?

In Vue.js 3.0.0+, the `destroyed` and `beforeDestroy` lifecycle hooks have been renamed
to `unmounted` and `beforeUnmount` respectively. Using the old names is deprecated and
may cause confusion or compatibility issues.

### Examples

Examples of **incorrect** code for this rule:

```vue
<script>
export default {
  beforeDestroy() {},
  destroyed() {},
};
</script>
```

Examples of **correct** code for this rule:

```vue
<script>
export default {
  beforeUnmount() {},
  unmounted() {},
};
</script>
```

## How to use

## Version

This rule was added in v1.35.0.
